If you have lost your vacuum charger, replacement is usually straightforward — as long as you confirm the correct electrical specifications.
Do not guess or buy based on appearance alone. Voltage and connector type must match exactly.
This guide explains how to replace a lost charger safely.
Step 1: Find the Required Voltage
Start by checking:
• The label on the vacuum body
• The battery housing
• The original product manual (if available)
Look for the output voltage requirement, such as:
• 18V
• 21.6V
• 25.2V
• 29.4V
The replacement charger must match this voltage exactly.

Step 2: Confirm the Connector Type
Even if voltage matches, the plug must fit securely.
Check:
• Barrel connector size
• Pin configuration
• Polarity marking (+ / –)
Do not force a connector that does not fit precisely.

Step 3: Choose OEM, Third-Party, or Universal
You typically have three options:
OEM charger
• Exact match
• Usually higher price
Third-party compatible charger
• Often lower cost
• Must list exact voltage and model compatibility
Universal adjustable charger
• Must be set to the exact voltage
• Connector must match
• Requires careful verification
For comparison guidance, see:

When a Universal Charger Makes Sense
A universal charger may be practical if:
• The vacuum model is older
• OEM chargers are discontinued
• Voltage is clearly labeled
However, adjustable voltage must be set correctly before use.

Common Mistakes After Losing a Charger
• Buying based on brand name only
• Assuming all chargers from the same manufacturer are identical
• Ignoring voltage specifications
• Guessing connector size
Electrical compatibility matters more than appearance.
Final Replacement Checklist
✔ Confirm exact voltage
✔ Match or exceed amperage
✔ Verify connector type
✔ Confirm polarity
✔ Avoid listings without clear output specifications
Losing a charger is common — but replacement must still be verified carefully to avoid damaging the vacuum battery.
